Among his latest inventions is a pressure reducer designed for use in pressurized pipelines. This device provides variable resistance to the flow of process fluids, such as steam or water, without the need for moving parts. The design features an elongate outer shell and an inner sleeve that is radially spaced from the outer shell. The outer shell is characterized by an outer annular wall with an open end and an end wall opposite the open end. The inner sleeve connects to the outer shell near the open end and defines a passageway leading into a cavity within the outer shell, with an outlet positioned away from the end wall. The outer annular wall and end wall are perforated with multiple flow holes, while the sleeve remains unperforated.

Another significant patent is for a floating ball valve seal that incorporates both dynamic and static C-seals. This seal assembly is designed for rotary ball valves with a top-mounted bonnet, allowing for easy installation and removal without needing to detach the valve from the pipeline. The assembly includes a seal ring that is biased toward the ball element of the valve, with a seal carrier positioned between the seal ring and the valve body. This innovative design features primary and secondary leak paths, each protected by auxiliary seals to prevent fluid flow.
